CARRlAGE-GEARING.

SPECIFICATION forming part of Letters Patent No. 281,667, dated July 24, 1883,

Application filed March 12, 1851.

useful Improvements in Carriage-Gearings, of I which the following is a specification.

My invention consists in mechanism for applying a well-known geometrical principle to carriage-springs, the object being, first, to supplement their motion, and thereby increase the ease and comfort of thoseriding thereon; sec- 0nd, to obtain such control over the motion communicated by springs that any desired amount thereof may be communicated to the body of the carriage.

The geometrical principle to which I allude is illustrated in the diagram attached to and making a part'of the accompanying drawings.

If a bar fastened at one end to an axle and the other end held horizontally from the axle be let drop, it will come to a standstill in a vertical position. Its first position, its fall, and last positionwill describe a quadrant. I therefore, for purposes of designation in this specification term such a bar a quadrantal arm.

In the diagram, the line from K to L repre sents a twelve-inch, from K to O a nine-inch, and from K to P a six-inch, quadrantal arm. Following the Vertical lines down with their corresponding quadrantal lines from L O P, it-

will be observed that I have control of the supplemental motion obtained, as before dethe spring I obtain four and one-eighth inches of motion, or down to 1, in place ofv four and five-eighth inches of motion of the twelve-inch arm at L, as before described, andfor a threeinch motion of the spring I obtain six and three-fourths inches of motion, or downto 3, in place of eight inches of motion of the twelveinch arm at L. From asix-inch arm, as at P, for one inch of motion of the spring I obtain three and one-half inches of motion, .or down to 1, in place of four and five-eighth inches of motion of the twelve-inch arm at L, and for three inches of motion of the spring I obtain five and one-fourth inches of motion, or down ,to 3, in place of eight inches of motion of the twelve-inch arm at L.

(No model.)

The foregoing describes, and the diagram illustrates, the principle by which I propose to obtain such control over motion communicated by carriage-springs that I can apply any desired amount thereof to the bodies of carriages.

In accompanying drawings, Figure 1 is'a plan of a carriage-gearing, and Fig. 2 a section illustrating-one of many ways of utilizing my invention. Fig. 3 is a plan view or diagram illustrating the principle of my invention.

Similar letters refer to similar parts in all the views. I

A represents the side bars of the gearing; B, the front and rear cross-bars.

D represents an eye or holder fastened to the cross-bars.

J represents another eye or holder fastened to the side bars, turned up at right angles.

E represents'a bolt,one inch in diameter, passing through with its head at J, and also passing through eye D and fastened there with a nut and screw-thread.

G represents a slotted carrier working on:

I through the holes represented for that pur-' pose and loaded, the pressure is communicated to the spring I, and from that to the qnadrantal arms, and thence to the carrier G, which,'by the vertical pressure at L, is drawn in a horizontal direction along the boltE; butthe spring F, whose end is inserted in the slot of the carrier G, opposes a flexible resistance, and here the contest between the spring, supplemented by the increased quadrantal motion, as set forth, and the jolts and jars of the road commences, but at very much increased ease and comfort to those riding in the carriage.

It is found that. a carriage-body hung in this manner has too much of arocking'motion fore and aft, and if one person be riding alone it being found that that will produce sufficient effect.

I claim as my invention 1.. The combination, with the central springs and quadrantal arms or bars having a sliding axis, of a spring or cushion arranged in the line of travel of the axis, so that it limits and governs the motion of the axis of the arm when thelatter comes in contact with it, as set forth.

2. The combination of the central springs arranged to carry the body of the vehicle, the quadrantal arms or bars connected thereto, and devices arranged to lengthen or shorten the travel of the axis of the said arms, as set forth.

3. The combination, with the quadrantal arms and the central. actuating-springs, of the arresting-bar attached to the body of the vehicle and bearing on the quadrantal arms, as set forth.

4. As an improvement in vehicle-springs, the combination of the end bolt, the carrier sliding thereon, with the spring F, acting against the carrier to limit the sliding movement of the same, as set forth.

5. As an improvement in vehicle-springs, the combination of the bolt E, the carrier G, sliding thereon, the transverse horizontallyacting spring engaging the carrier, the quadrantal arms or bars pivoted to the carrier, and the central springs, I, set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
